Abstract: | Combined zerographic measurements and a delayed-collection field technique has been applied to a-As2Se3. The data shows that the zero-field quantum efficiency is 0.45±0.02. The measured field and temperature dependence gives a best fit to the Onsager theory with for Φ0=1. Non-geminate recombination was studied using a delayed-collection field technique as a function of the time delay of the collection field. The results indicate a remarkably long recombination lifetime≈1 sec at room temperature which is diffusion-controlled. |
